Hoʻonui i ka hydrophilicity o nā mea mālama UV

Loaʻa i ka UV curable coatings nā mea maikaʻi o ka wikiwiki o ka hoʻōla ʻana, ka launa ʻana i ke kaiapuni, ka mālama ʻana i ka ikehu, ke kumu kūʻai haʻahaʻa, a me nā mea ʻē aʻe ", a ua hoʻohana nui ʻia i ka pepa, ka lāʻau, ka plastik a me nā māla uhi ʻē aʻe.ʻO ka ʻōlelo maʻamau, hiki ke hoʻololi pololei ʻia ka resin wai photosensitive i resin i hoʻōla ʻia ma ka waiho ʻana ma lalo o ke kukui UV i ka mahana o ka ea ʻO ka maʻamau, ʻaʻole ia i loko o nā mea hoʻohuihui kūlohelohe no ka lā hoʻokahi.Me ka nānā ʻana i nā pilikia kaiapuni, ʻo ka noiʻi, ka hoʻomohala ʻana a me ka hoʻohana ʻana i kēia kaʻina hana "'ōmaʻomaʻo" e pili ana i ke kaiapuni e lilo i mea hohonu a kaulana.ʻO ka uhi hydrophilic kahi ʻano o ka uhi hana i hoʻomohala wikiwiki ʻia i nā makahiki i hala iho nei.Hana ʻia ka uhi hydrophilic kuʻuna ma ka hoʻomoʻa ʻana i ka resin hydrophilic ma 200C no ʻumi kekona, a laila hoʻōla a hoʻopaʻa ʻia e hana i kahi kiʻiʻoniʻoni.ʻOiai ʻo ke ʻano o ka hoʻomākaukau ʻana he ʻenehana makua a me ka hydrophilicity maikaʻi, hoʻopau ia i ka ikehu nui, hoʻokaʻawale i nā mea hoʻoheheʻe organik a maikaʻi ʻole ke kūkulu hale.ʻAʻole hiki i ka hoʻomākaukau ʻana i nā uhi hydrophilic kūlohelohe maʻemaʻe e ka UV curing a me ka cross-linking ʻaʻole hiki ke hoʻohana wale i nā pono o ka curing UV, akā hoʻokō pū i nā koi o ka hydrophilicity.Ma kēia pepa, ua ʻae ʻia kahi manaʻo synthesis hou.Ma muli o ka copolymer acrylate kaumaha molekala haʻahaʻa, ua hoʻokomo ʻia ka monomer photosensitive, a laila ua hoʻokumu ʻia ke kiʻiʻoniʻoni hiki ke kiʻi ʻia e hoʻomākaukau i nā uhi hydrophilic.Ua noiʻi ʻia nā hopena o ka hoʻokomo ʻana o GMA, monomer ratio, active diluent type a me ka ʻike e pili ana i ka hydrophilicity a me ka pale wai o nā uhi.

ʻO nā mea hoʻomaʻemaʻe UV maʻamau he hydrophobic, kahi pili pili i ka hoʻohui ʻana o kā lākou hoʻokumu ʻana.Pono e hoʻohana ʻia nā Photoinitiators i ke ʻano hoʻōla UV.I kekahi manawa, i mea e hoʻonui ai i ka mālama ʻana i ka ʻili, e hoʻohui ʻia kekahi mau mea hoʻohui e hoʻoikaika i ka hoʻōla ʻana i ka ʻili.ʻO kēia mau photoinitiators a me nā mea hoʻohui he hydrophobic maʻamau, a ʻo nā huahana decomposition o nā photoinitiators e neʻe i ka ʻili o ka mea hoʻōla, pēlā e hoʻoikaika ai i ka hydrophobicity o nā mea hoʻōla UV.ʻO ka resin a me ka monomer i loko o ka UV curing formula he hydrophobic ma ke ʻano maoli, a ʻo ka huina pili ma waena o 50 a me 90 degere.

ʻO Styrene sulfonate, polyethylene glycol acrylate, acrylic acid a me nā mea ʻē aʻe he hydrophilic iā lākou iho, akā ke hoʻohana ʻia i nā mea hoʻōla UV, ʻaʻole e hoʻonui nui ʻia ka hydrophilicity o nā mea i hoʻōla ʻia, a ʻoi aku ka nui o ka huina pili ma mua o 50 degere.

ʻO ka hydrophilicity, he maʻalahi nā molekala a i ʻole nā ​​​​hui molekele e komo i ka wai a hiki ke hoʻoheheʻe ʻia e ka wai.ʻO ka ʻili o nā mea paʻa i hoʻokumu ʻia e ia mau molekala e maʻalahi i ka wai.ʻO ka hoʻohana ʻana i nā uhi he nui e pono ai ka ili waiwai e loaʻa ka hydrophilicity maikaʻi, e like me ke kiʻiʻoniʻoni, paʻi offset, nā mea hoʻopili kūikawā, nā mea biocompatible, etc. me ka mika huina.ʻO nā mea me nā kihi pili ma lalo o 30 degere ke manaʻo ʻia he hydrophilic.
